The laws of the Quaker state and the contracts that everyone signs with the University.
And as far as the "actual Police", the PSUPD are the actual Police on the Penn State campus. There is no other.
The campus police are glorified rent a cops; and no wonder Sandusky abused children on Pedo State Campus - he knew they had his back as far as not reporting it to the actual Police.
Paterno did the bare minimum required by law, if that - as Schultz wasn't actually the Police - he oversaw the campus police. Sort of like if you had to report something to the Police but you told the deputy mayor, because the deputy mayor oversaw the Police.
The bare minimum required by law, vs your insistence that Paterno did the maximum allowed under the law. Cite the law.
